WANTED: Template for Elephant ears for a 400 BB

Stamierdodge,
I'm looking for a template that I can layout on some aluminum and then have my buddy use his CNC machine to cut them out. I would prefer the ears style vice the whole onepiece motor plate. I don't know what thickness I'll be using but probably around 1/4"-3/8". or If somebody has any suggestions on thickness I'll take it.
Thanks
TAZZ
